Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mutton
- Supplies the meat, which becomes tender as it simmers in the sauce.
- Onions
- Browning them adds sweetness and a deeper savoury base to the curry.
- Butter
- Fat for frying the onions, carrying flavour and helping them brown.
- Curry powder
- Provides the spice aroma and flavour that defines the dish.
The step that matters
Frying the onions until brown. Onions that are pale lack depth, while burnt ones taste bitter. Slow, even browning lets sugars caramelise and build savoury flavour that carries through the whole curry.
Swap the onion
How well each one fits the dish's main ingredients (mutton, butter):
- Potatofits about as well
- Leekfits about as well
- Onionthe original
- Shallotfits less well
Fit is the average pairing score against mutton, butter. Candidates are from the same food group and used in at least 100 recipes.
